ERNEST ALWEN VE'ITEB, OF BROOKLYN, YOZRI'L HAIR CLIPPER.

Application filed January 15, 1924. Serial No. 885,412.

Z '0 (6% whom, it may concern Be it known that I, Ennns'r A, Vrxrrnn, acitizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Hair Clipper, of which the following is afull, clear, and exact description.

This invention has. relation to hair clipping devices and has particularreference to hair clippers of the reciprocatory knife ()ne of theoutstanding objects of the present invention is to provide a clippingdevice in which the operating handles are so associated therewith as todispose the same in laterally projecting relation to the outters wherebythe clippers may be used by a person in the operation of cutting orclipping his own hair.

As a further object the invention contemplates a hair cutting device inwhich the operating handles are detfachably and reversibly associatedwith the cutting elements or knives to permit of their reversal and usewith either hand.

As a still further object the invention aims to provide a hair clippingdevice which is comparatively simple in its construction and mode ofoperation, which is inexpensive to manufacture and produce, and which ishiggly eflicient in its purpose.

ith the above recited and other objects in view, theinvention resides inthe novel construction set forth in the following specification,particularly pointed out in the ap pended claims and illustrated in theaccompanying drawings, it being understood that the right is reserved toembodiments other than those actually illustrated herein to the fullextent indicated by the general meaning of the terms in which the claimsare expressed.

In the drawings 7 Figure 1 isxa perspective view of a hair clipperconstructed in accordance with the invention.

Fig. 2 is a plan view of the operating handles removed from thecuttingelements.

Fig. 3 is a diagrammaticplan view illustrating the manner in which theoperating handles may be reversed.

Referring to the drawings by characters ofreference 10 and 11 designaterespectively a pair of blades each having a plurality of cutting teeth12 at one edge thereof. The

blade 11 which will be hereinafter termed the movable blade issuperimposed on the blade 10 which will be hereinafter termed thestationary blade and is connected with said stationary blade forreciprocation whereby the cutting teeth coact to set up a shearingaction for clipping or cutting the hair. As illustrated, the stationaryblade 10 is provided with a central upstanding shaft or trunnion 13which extends through a longitudinal slot in the movable blade 11 andwhich is threaded for a purpose to be hereafter disclosed. The upperface of the blade 11 is longitudinally grooved as at 14 to receivetherein the downturned guide flange 15 at the forward edge of theretaining and guiding plate 16 which overlies the blade 11. The rearedge of the plate 16 is provided with depending feet 17 which arereceived in the notches at the rear edge of the stationary blade 10. Thetrunnion or threaded shaft 13 projects through a central opening in theplate 16 and receives thereon an adjusting nut 19 between which and theplate a bowed leaf spring 20 is interposed for exerting a pressure onthe plate 16 whereby its flange 15 in turn serves to impinge the blade11 against the blade 10.

By turning the nut 19 in opposite directions the pressure may beincreased or decreased to obtain the best results from the clipper. Thenut 19 is provided with a reduced upwardly projecting annular boss 21and the plate 16 is provided with apair of upwardly projecting eccentrictrunnions 22 and 23 adjacent spaced from the boss 21. The movable blade11 is further provided with a rear wardly projecting car 24 having abearing aperture 25 extending vertically therethrough. A pair ofmanipulating handles 26 and 27 are pivotally connected at one end by apivot sleeve 28 and are formed at their opposite free ends with fingerreceiving loops 29. The handle 27 which will be hereinafter termed thestationary handle has secured thereto adjacent its free end a leafspring 80 which spring bears at its free-end against the movable member26 at a point adjacent the pivoted end thereof whereby the free ends ofthe handles are normally swung apart. A stop lug 81 is provided on thestationary handle member for limiting the relative separation or openingmovement of the handle members.

The internal diameter of the pivot sleeve its rear edge andequidistantly 28 is of a size to snugly fit over the boss 21 and thestationary handle member is further provided with an aperture 32 whichis appropriately spaced from the plvot sleeve 28 to engage over eitherof the eccentric trunnions 22 or 23 whereby the stationary handle memberis coupled to the stationary blade against relative movement withrespect thereto. The movable handle member 26 is provided with a lateralextension 33 at its pivoted end, which lateral QX'tGllSlOll 13 formedwith a head 34 having oppositely projecting vertical lugs 35 and 36which are adapted to respectively engage with the bearing aperture inthe ear 2 1 when the handle members are reversibly associated with theclipper blades, Under this con struction it is obvious that when thehandle members are operatively associated with the clipper blades theyproject from the sides thereof so that the cutting teeth protrude at aright angle to the length of the handle members, thus facilitating theuse of the device in the operation of a person cutting his own hair. Inorder to provide means for retaining the handle members in associatedrelation with the clipping blades, a retaining knurled nut 37 isthreaded upon the free end of the threaded shaft or trunnion 13.

In use and operation, the handle members are associated with the bladesby engaging the pivot sleeve 28 over the boss 21 and simultaneouslyengaging the aperture 32 in the stationary handle member 27 over theeccentric trunnion 23 with the depend ing vertical lug 36 engaging inthe bearing aperture 25 of the ear 2t. The nut 37 is then threaded inplace. The operator inserting the finger and thumb of the right hand inthe loops 29 may then conveniently operate the device to clip upwardlyat the back of the head. The relative opening and closing movement ofthe handle members will effect through the engagement of the lug 36 andthe'bearing aperture 25 of the ear 2s relative reciprocation of theblade 11 and its teeth 12 with respect to the blade 10 and its teeth 12whereby the shearing and cutting action is effected. When it is desiredto clip upwardly with the, left hand, the retaining nut 37 is removedand the handle members arranged in reverse relation by engaging theaperture, 32 over theeccentric trunnion 22 with the lug and the bearingaperture 25 of the ear 24, it, of course, being understood that thepivot sleeve is also engaged over the boss 21 and the nut 37 replaced.

From the foregoing it will thus be seen, that a clipping device has beenprovided in which the operating handle members are capable of detachableand reversible association with the blades and protruding from the sidesthereof in order to afford means which permits of the use of clippers inthe operation of cutting ones own hair,
